... various vertebrates during this period. Specifically, the salinity of environments spanning fresh to shallow marine water is difficult to discern from sedimentological and paleontological analyses alone. Here, we analyze rare earth elements and yttrium (REY) as well as stable oxygen and sulfur isotope...

... of abundant yttrium phosphate nanoparticles identified as xenotime, forming large globular aggregates that reach a few microns in diameter; these xenotime aggregates also host trace concentrations of Zr, Dy, Er, Yb, and Ce. Further, rhabdophane nanoparticles were detected that host predominantly light REEs...

...Dengfeng Li; Jinzhou Peng; David Chew; Yongjia Liang; Pete Hollings; Yu Fu; Yanhui Dong; Xiaoming Sun Abstract Deep-sea sediments rich in rare earth elements and yttrium (REY) are promising mineral resources that are believed to be associated with the burial of fish debris. However, the nature...

... South China granite The rare-earth elements (REE), generally defined as the lanthanides plus yttrium (Y), are considered critical raw materials because of their extensive applications in renewable energy solutions and modern technologies ( Kalvig and Machacek 2018 ). Recently, concerns over...

... and 3-D) reconstructions of the morphology, mineralogy, trace element geochemistry, and taphonomy of permineralized stromatolites from the lowermost horizons of the ca. 3.5 Ga Dresser Formation, Pilbara, Western Australia. Rare earth element plus yttrium compositions suggest a restricted...

... plotted on a Sr/Y–Y diagram ( Fig. 13B ), most of these samples fall into the adakitic range ( Defant and Drummond, 1993 ; Richards and Kerrich, 2007 ), with Sr/Y ≥20 and Y ≤18. Figure 13. (interactive) Yttrium variation diagrams. (A) Y is generally depleted with differentiation, marked...

... of such formations are associated with seafloor cold seeps. Here, we document petrographic, rare earth element + yttrium (REE + Y), carbonate clumped isotope temperature (T Δ47 ), and carbon-isotopic evidence from a shale succession in southern Tibet spanning a ~28 m.y. interval (ca. 113–85 Ma) that coincided...

... and anions. Some element contents – including those associated with VMS deposits – differ depending on the filtration technique used (e.g. As, Fe, Pb, rare earth elements and yttrium (REY)), some are equally affected by both techniques (e.g. Cu, Ni, Zn), and some are unaffected by filtration (e.g. Ba, Ca, Mn...

... of the parental rocks for the E k 2 shale belonged to the Continental Island Arc. The distribution patterns of trace elements and rare earth elements + yttrium (REEs + Y) are close to the intermediate igneous rock. The ratios of Al 2 O 3 /TiO 2 ranging from 21.41 to 27.59 with a mean value of 23.93 also...

The ΣREE contents in all bulk samples ( Fig. 6 ) are 2–4 times the respective PAAS values ( Taylor and McLennan, 1985 ). They are the lowest in carbonate ores (222...
